Last updated Apr 6, 2026|Official source

Summary

Creates a National Multimodal Freight Network that the Assistant Secretary for Multimodal Freight must set up. The network is meant to help States spend money wisely, guide freight planning, set federal investment priorities, and support national freight goals. The Assistant Secretary must ask for public input from shippers, carriers, ports, airports, railroads, metropolitan planning groups, local governments, and States, publish a draft for comment, and use measurable data about where goods start, end, and move in supply chains when picking critical routes and facilities. The Assistant Secretary must weigh factors like origins and destinations, volume and value, access to borders and ports, economic importance, links to manufacturing, agriculture, energy areas, intermodal connections, chokepoints, and nominations from States or regional groups. States can propose extra routes but must consider nominations from planning organizations and facility owners, make sure additions fit their transportation plans, and submit a list and certification. States may label some rural roads as critical if they meet several criteria (for example, serving energy or major agricultural or intermodal sites). A State’s extra mileage cannot exceed 30 percent of the network mileage in that State as set by the Under Secretary. The Assistant Secretary must review and redesignate the network no later than 5 years after the first designation and every 5 years after that.
